摘要
A color printing system includes a discrete CMY color printer, a LAB color error diffuser, and a LAB/CMY converter. The diffuser includes an image compensator, a vector color space reverter, an error calculator, and an error diffuser. The vector color space reverter provides for error diffusion in a LAB color space that is different from the CMY color space of the printer. The perceptual linearity of the LAB color space provides for enhanced color fidelity in the printed image. In addition, color conversion and error diffusion are performed together, minimizing computational error accumulation and maximizing computational throughput.
